E-MU Systems Proteus Master Performance System Plus (The X-Files Synth!) 1991 Black

This is the X-Files synth. - Mark Snow used this model to score the X-Files.
The original Myst was scored on a Proteus MPS just like this one.


You will be hard pressed to find one of these in this great condition.  The power supply is brand new.  The internals have been professionally cleaned. 

Every key, jack, button, slider and display works perfectly.
KEYBOARD 61 keys with velocity and aftertouch. Main panel features a 16 x 2 LCD display, 30 push button, 1 volume slider and 1 data encoder.
Rear panel terminal connectors:
- main signal out
- Midi interface
- headphones
- 1 pedal switch input (e.g. SUSTAIN)
- 1 pedal input (e.g. VOLUME)
- headphones (front)

TECH main core based on a Motorola MC68000 manages up to 32 channels polyphony.
A MPS voice is composed by 2 elements samples "primary" + "secondary" with some edit parameters:

- pitch tuning (fine and coarse)
- keyzone assignments
- start delay
- stereo panning
- mix level
- reverse playback
- chorus mode (it fats voice up)

WAVETABLE internal 4Mb ROM - 125 PCM waves at 39 kHz / 16 bits resolution.

PCM wavetable contains all kind of sounds samples including: piano, string, sax, trumpet, brass, guitar, bass, organs, drums, percussions and basic waveforms (e.g digital, square, harmonics, short-cycled).

PERFORMANCE multitimbric system up to 16 parts some special functions:

- solo monophonic mode (for: OSC1/OSC2/BOTH)
- crossfade balance between primary and secondary
- pitchbend range (+/- 1 OCT)
- 3 footswitch assignable controls (eg: sustain, portamento, hold...)
- key velocity control
- FX amount
- Keyboard Split zone+4 preset velocity curves
- Quickeys function: enable a special 4 patches setup recall with zone assignment

LFO 2 delayed modulators (shapes: sin, triangle, saw, square and random) for pitch with variable amount and random fluctuation.

ENVELOPE 3 EGS 4 segments + 2 times called DAHDSR which stands for Delay, Attack, Hold, Decay, Sustain, and Release.
- EG1 primary sample amplitude
- EG2 secondary sample amplitude
- EG3 AUX (assignable) EG can be assigned to the matrix control.
TIP: Special "Alternate" mode plays the EG forward and then Backward.

EFFECT unlike the previous rackmount, MPS features a double DSP engine for effects A/B:
A- REVERBS delay, reverb (plate, chamber, hall, warm), stereo chorus, EQ, echo.
B - VARIOUS: flanger, chorus, phaser, fuzz, ring modulator, cross delay, EQ.

MIDI full sysex commands and some basic CC controls including: panning, modulation and 4 assignable controllers ABCD

MATRIX the "real-time control" allows some special modulation routings:
